PS Audio Perfect Wave Dac output level

I am having a difficult time finding the output voltage of the psa pw dac. I will be using it with a preamp so the variable output feature of the dac will not be used, at least in the short term. Thank you in advance for your help.
According to the manufacturer in their forums, with the volume level set to '100' (the maximum) the unbalanced output voltage is 2.8v and it doubles to 5.6v when you utilize the balanced output.
Bill, thank you very much for the information.
